- What it's about
This case concerns the proper venue for small oil refineries to challenge the EPA's denial of their hardship exemptions from the Renewable Fuel Standard program. The Supreme Court determined that these challenges must be heard in the D.C. Circuit Court of Appeals because the EPA's denials were based on determinations with nationwide scope or effect.
Question presented
Should challenges by small oil refineries seeking exemptions from the requirements of the Clean Air Act’s Renewable Fuel Standard program be heard exclusively in the U.S. Court of Appeals for the D.C. Circuit because the agency’s denial actions are “nationally applicable” or “based on a determination of nationwide scope or effect”?
